Just to add on to that, VIT is also involved in the Jump potency formula, and 2*VIT is the amount of HP healed with Chakra, as well as the amount of magic damage absorbed by Rampart.

Can't you suggest to those who write the notes that being gratuitously vague isn't a Good Thing, it's infuriating when what they write it totally ambiguous, it's worthless as presented because no one has a clue what the change actually is, hence the speculation and 'negative vibes' such update notes generate.
It isnt the first time such an issue has happened, I recall a similar reaction occured when SE had announced that they were changing the first 6 dynamis areas. But I think when they say they're going to do something, it's more along the lines that "Were going to change this, but we haven't decided how yet." Which is good and bad in my opinion, besides getting a rise out of the general populus over the speculation of "this is the gaming apocolypse", it feeds SE a bunch of ideas on people's opinions about the change, players reasonable ideas on what they think might change (which might make SE go hey thats an even better idea than what we planned) , and how much players think it would overall effect the game.
